Not really finished (nrf), a larval-lethal mutation in zebrafish generated by retroviral insertion, causes specific retinal defects. Analysis of mutant retinae reveals an extensive loss of photoreceptors and their precursors around the onset of visual function. These neurons undergo apoptosis during differentiation, affecting all classes of photoreceptors, suggesting an essential function of nr...

Bremer K, Monk CT, Gurd BJ, Moyes CD. Transcriptional regulation of temperature-induced remodeling of muscle bioenergetics in goldfish. Am J Physiol Regul Integr Comp Physiol 303: R150 –R158, 2012. First published May 23, 2012; doi:10.1152/ajpregu.00603.2011.—Central to mammalian mitochondrial biogenesis is the transcriptional master regulator peroxisome proliferator-activated receptor (PPAR)co...

NF-kappaB repressing factor (NRF), a nuclear inhibitor of NF-kappaB, is constitutively expressed and is implicated in the basal silencing of specific NF-kappaB targeting genes, including IFN-beta, IL-8/CXCL8, and iNOS. Little is known about the regulation of NRF and its role in response to stimuli. Airway smooth muscle (ASM) is a rich source of inflammatory mediators that may regulate the devel...

Prolonged oxidative stress favors tumorigenic environment and inflammation. Oxidative stress may trigger redox adaptation mechanism(s) in tumor cells but not normal cells. This may increase levels of intracellular antioxidants and establish a new redox homeostasis. Nrf-2, a master regulator of battery of antioxidant genes is constitutively activated in many tumor cells. Here we show that, murin...

The Escherichia coli K-12 nrf operon promoter can be activated fully by the FNR protein (regulator of fumarate and nitrate reduction) binding to a site centered at position -41.5. FNR-dependent transcription is suppressed by integration host factor (IHF) binding at position -54, and this suppression is counteracted by binding of the NarL or NarP response regulator at position -74.5. The E. coli...

The present study describes an investigation by fluorescence quenching, circular dichroism and UV-visible spectroscopy of the interaction between norfloxacin (NRF) and human serum albumin (HSA) in the presence of electromagnetic fields (EMFs). The results obtained from this study indicated that NRF had a strong ability to quench HSA at λ(ex) = 280 nm. In addition, a slight blue shift occurred, ...

The goal of this study was to compare the effectiveness of three treatments aiming to reduce nasal airflow resistance (NR): an external nasal strip device (Respir+), an internal nasal mechanical dilator (Nozovent), and a topical decongestant (Pernazène). NR was estimated by active posterior rhinometry at both a 0.5 L/s flow (NRF) and a 1 cm H2O pressure (NRP), under four conditions: in the basa...

Transcriptional regulation of the interferon-β (IFN-β) gene is characterized by strict constitutive repression and virus-specific activation. Previous studies have shown that the IFN-β promoter is constitutively repressed by a negative regulatory element (NRE). Isolated NRE acts as a constitutive and positionindependent silencer on the NF-κB-binding sites. Here, we describe the identification a...

SKN-1/Nrf plays multiple essential roles in development and cellular homeostasis. We demonstrate that SKN-1 executes a specific and appropriate transcriptional response to changes in available nutrients, leading to metabolic adaptation. We isolated gain-of-function (gf) alleles of skn-1, affecting a domain of SKN-1 that binds the transcription factor MXL-3 and the mitochondrial outer membrane p...
